Best Alternatives to ZX-XH2.54-4PZZ

Package: Through HoleMegastarInterconnectsNumber of Positions: 4Pitch: 2.54 mmMounting Type: Through HoleCurrent Rating: 2 AVoltage Rating: 250 V AC/DC

ZX-XH2.54-4PZZ is a standard 4-pin, 2.54mm pitch straight header from Megastar, commonly used for wire-to-board connections. Several alternatives exist with similar or upgraded electrical ratings.

AI replacement insight

Package riskmedium

Footprint must be verified from datasheet for all alternatives.

Electrical risklow

Most alternatives match or exceed voltage/current ratings.

Can it be replaced directly?

ZX-HA2.54-4PZZ from the same manufacturer is a strong candidate, matching all key specs. However, always verify the datasheet drawing.

Best replacement path

Upgrade to a 3A rated part like WAFER-XH2.54-4PLB for more current headroom and better housing material.

Main risk

The primary risk is mechanical incompatibility; even with the same pitch and pin count, housing dimensions or pin lengths can vary.
